Give examples of energy transformations

Answer 1

Here are some examples of energy transformation:

• Potential energy of a waterfall transforms to kinetic energy, moving the turbines, and then its transformation to electric energy through the turbo-generator system.
• Electrical energy goes through a toaster and turns into thermal energy or heat then sound when the toast is done.
• When you rub your hands together, your hands become warm. Mechanical energy due to motion is changed into heat.
• A television: Electrical energy--> light energy--> sound energy
• A firecracker: Heat to Chemical to Sound/Light. Reason being is that the source of the Chemical PE is heat in the match, which lights the fuse. Chemicals then burst when the heat hits the firecracker, and it creates a crack and it sparks.
• A light bulb: electrical to light and heat
• The energy used to blow a Trumpet is transformed into sound.
• Sound: Clang two cymbals together. Part of the energy from the collision is transferred into sound.
• Heat: I skid on my knees on a wooden floor. I will eventually come to a stop, because the energy I used to skid is lost to friction and heat (which help cause those nasty wood burns).
• Kinetic: I jump out of a plane with a parachute. My potential energy is transformed tokinetic energy as I fall.
• Potential: I go up an elevator. My potential energy increases the higher I am from the ground.
• Chemical: Two hydrogen atoms react and form one dihydrogen molecule. Energy is stored in the bond formed between the two atoms.
• Nuclear: Nuclear power plants use nuclear fission and fusion in controlled reactions to generate energy.

Answer 2

chemical energy is transformed into movement while running, etc.
